Purinoceptor P2K1/DORN1 Enhances Plant Resistance Against a Soilborne Fungal Pathogen, Rhizoctonia solani.

ABSTRACT: The purinoceptor P2K1/DORN1 recognizes extracellular ATP, a damage-associated molecular pattern (DAMP) released upon cellular disruption by wounding and necrosis, which in turn, boost plant innate immunity. P2K1 is known to confer plant resistance to foliar biotrophic, hemi-biotrophic, and necrotrophic pathogens. However, until now, no information was available on its function in defense against root pathogens. In this report, we describe the contribution of P2K1 to resistance in Arabidopsis against Rhizoctonia solani, a broad host range, necrotrophic soilborne fungal pathogen. In pot assays, the Arabidopsis P2K1 overexpression line OxP2K1 showed longer root length and a greater rosette surface area than wild type in the presence of the pathogen. In contrast, th
